Lab Investigation


Put 10 ml of water into two cylinders

Make a hypothesis of volume of water when combined

Before you combine the two liquids write down your hypothesis

I believe it will be 20mL because when you add 10 to 10 it equals 20.

CORRECT√


Measure out Isopropyl alcohol 10 ml in each cylinder

Then write hypothesis

Then combine

I believe it will be 20mL because when you add 10 to 10 it equals 20.

CORRECT√


Measure out 20 ml of water

Make Hypothesis

Combine with the alcohol

I believe it will be 40mL because when you add 20 to 20 it equals 40.

INCORRECT

Compost info

Compost is usually composed of organic waste mixed together to form soil. Compost is usually used in gardening.

Most compost’ers usually use a special bin called a composting bin for their compost. Compost is created when various decomposers such as mushrooms, decompose the organic materials.

Compost can be rich in nutrients. It is used in gardens, landscaping, horticulture, and agriculture. The compost itself is beneficial for the land in many ways, including as a soil conditioner, a fertilizer, and as a natural pesticide for soil.

Worms are sometimes used to quicken the decomposing process, this compost, which is the product of worm waste, is called vermicompost.

At its most essential, the process of composting requires simply piling up waste outdoors and waiting for the materials to break down from anywhere between 6 weeks or more. Modern, methodical composting is a multi-step, closely monitored process with measured inputs of water, air and carbon- and nitrogen-rich materials, but this is not required to create compost..

Human urine has more plant-soluble substances than feces. It does not attract flies, like feces does, and also does not stink for long.
